+/**
+ * Wrapper for compile-time-constant strings.
+ *
+ * Const is a wrapper for strings that can only be created from program
+ * constants (i.e., string literals).  This property relies on a custom Closure
+ * compiler check that {@code goog.string.Const.from} is only invoked on
+ * compile-time-constant expressions.
+ *
+ * Const is useful in APIs whose correct and secure use requires that certain
+ * arguments are not attacker controlled: Compile-time constants are inherently
+ * under the control of the application and not under control of external
+ * attackers, and hence are safe to use in such contexts.
+ *
+ * Instances of this type must be created via its factory method
+ * {@code goog.string.Const.from} and not by invoking its constructor.  The
+ * constructor intentionally takes no parameters and the type is immutable;
+ * hence only a default instance corresponding to the empty string can be
+ * obtained via constructor invocation.
+ *
+ * @see goog.string.Const#from
+ * @constructor
+ * @final
